This invention relates to metal boxes of the sliding cover type andconstitutes an improvement on my inventions set forth in my applicationsSer. No. 13,751 filed Mar. 29, 1935 for Boxes and Ser. No. 21,653, filedMay 15, 1935 for Boxes.-

'Ihe primary object of the present invention is to provide such aconstruction in a box of the type stated as to prevent twisting orcanting of the top and body with relation to each other; 10 to outwardlyspread, flare, bend or offset portions of the body to prevent suchtwisting or canting; to offset or downwardly depress the extreme lowerouterface of a portion of said two diameter curl to aid in preventingsuch twisting l or canting; to bend portions of the small portions ofthe two diameter curl outward toward or iiush with the plane of theextreme outer face portions of the immediately adjacent portions of thelarge diameter portions of said curl to aid in preventing such twistingor canting or to prevent such twisting or canting; to provide roundededge faces which will not scratch or mar the lithographed or otherspecial nish of the boxes as the same issue from the forming machinesand drop into the receiving baskets or receptacles, the stop elements ormembers being so formed, positioned and disposed that no sharp orscratching or cutting faces or edges will come in contact with or maradjacent box parts.

Referring now in detail to the drawing, A desig- 55 nates the body ofthe box; B, the sliding top;

C, the usual dispensing display card; D, the usual lugs or ribs struckor pressed out laterally from the sides of the body to cooperate withthe body edge curl or the side iianges of the top B to hold the box inthe usual receiving openings in the display card C; E, the usual snapcatch lug or latch stamped down or inward in the top B to engage andride up over the end edge curl as the top Bis shoved toward closedposition and, as soon as the top B reaches closed position, 10 snappingdown by the resiliency of the top B and tting inside of, and engagingthe adjacent end face of body A to hold the top B closed againstaccidental or unintentional displacement but being adapted to similarlyride up over the top of said end face to permit the top B to be openedon pressure being applied in the reverse direction t0 open the box.

The body A has its edge portion rolled or curled with a two diametercurl, the larger diameter I being separated by the smaller diameter 3 oneach side of the body, the length of the smaller diameter curl portions3 preferably corresponding substantially to the length of movement ofthe top B, and the larger diameter portions I respectively extendingabout the respective end portions of the body A and having sharp abruptend shoulders formed by the edge of the metal as rolled or curled intosuch larger diameter portions I. This two-diameter curl may be formed inany suitable manner. One method is illustrated in Fig. 7, wherein thebody blank A is formed with relatively long outwardly curved or flaredend and side portions I' to form the larger diameter edge curl portionsI and 5 intervening intermediate shorter side portions 3' to form thesmaller diameter curl portions 3, some of the metal being cut out forthe length of each said portion 3', leaving a shorter length of metal tobe formed into the small diameter 40 curl portions 3.

The sliding top or cover B will preferably be slightly arched in formwith an outwardly and downwardly inclined marginal panel or panels 5extending completely around it and will preferably be springy orresilient as a whole preferably cross-wise and preferably lengthwise andat its side portions is formed with downwardly and lnwardly curved sideflanges 2 to t about and below, and slidably receive, said two-diametercurl I, 3 of the body A. Said flanges 2 have their respective lowerinner portions cut out or interrupted in the preferred form preferablydefined on one side of the cut or interruption by a straight verticalsharpor abruptsquare edge, said edge and adjacent supporting portionbeing bent inward `tions will lie appreciably closer to the lower face`portions of the adjacent parts of the 'said large flange 2 torespectivelyengage the cooperating opposed faces of the shoulders Iaformed by the `abrupt or sharp or raw end faces or edges of the largerdiameter portions I of the two-diameter edge curl. Such shoulders IWillbe so disposed lengthwise of the flanges 2 that in the closed positionof the top B they will lie between the shoulders I a and closelyadjacent to said shouldersfof one large diameter curl portion I and, inthe open position of the cover B, will positively engage with theshoulders Ia of the other large diameter` portion I, any pressureexertedon the top or cover B in an attempt to force it open be-k yond thispoint simply serving to force the opposing faces of the tongues orshoulders 4 and the cooperating shoulders la into tighter biting orcutting engagement effectually preventing any riding of one set of stopshoulders or faces beyond the other and cooperating set of stopshoulders or faces.

Since in the open position of the top or cover B the inner ends of theside flanges 2 will lie between the shoulders la and said Lflanges 2 insuch case would' only engage the large diameter por' tion Ir of the bodyA adjacent one end thereof and having in mind that these boxes are to beproduced in great quantities with consequent lack of minute exactprecision there would be a resultant slight play in a twistingtransverse direction between the body A and top B when the top yB isopen, rendering the top subject to becoming twisted or canted withrelation to the body A and` therefore the top B and body A are so formedand associated as to prevent any such degree of twisting or canting aswillcause a binding or jamming of these parts or objectionably interferewith their easy and emcient relative move ment incident to the openingandclosing of the box. To the immediately foregoing end preferably theupper portions of the sides of the body intermediate, and from pointsclosely adjacent to, the shoulders Ia will be outwardly flared, bent oroffsetas at 3a, this involving the outward bending oi.' most of each ofthe small curl `portions ,3 as

well as the offsetting or depressing of most ofv said portions 3 towardthe bottom of the body A, with the result that, except for their extremeend portions immediately'adjacent the shoulders Ia, lthe extreme outerside faces of said portions 3 will lie flush or substantially flushwith' the corresponding faces of the adjacent parts of the largediameter portions I and the lower face pordiameter portions I, thustaking up practically all of the' play in a horizontal plane and'most ofthe play in avertical plane.

` It may be desirable for considerations of economy of manufacture tosimply provideone side of spending side ange 2 of the top B Vwith a sformed with a stop tongue or shoulder 4,'such side of thev body A onsetat 3a and providedwith the small diameter curl portion 3 outwardly anddownwardly bent between the shoulders Ia being illustrated in Fig. 5 forinstance.

4The top B may be formed with a hook type or form end 'stop F adjacentthe little lug jor catch E to engage the end of the body A or theadjacent portion of the edge curl to prevent sliding move-A ment of thetop B in the reverse direction beyond closed position.A

In practice, after the body A and top have been formed as'above, oneside flange 2 of the top will be applied to or hooked under the largediameter curl portions I on one side of the body A with the shoulder ortongue l of said flange 2 disposed between the shoulders Ia of saidlarge diameter curl portions I, the other side flange2 of the top B willbe brought to rest on the top of the curl portions I on the other sideof the body A, and then pressure will be applied gently, as by hand, tocause the latter flange 2 to snap about and under said curl portions Iand the curl portions 8,

and the assembly of the box will be complete.' The foregoing `is thepreferred mode oi' assembly.

l though of course the box may be assembled by any mode' foundpractical'.

vPreferably the top B will be so formed and of vsuch size that whenclosed the inclined marginal partially lengthwise of the sides and twosmall diameter portions on the sides interposed between they opposed endfaces of said 'large portions, said end faces being the exposed edges ofthe curls of the large diameter portions and constituting abrupt sharpbody stop. shoulders ,Y having raw edges extending laterally in a planesubstantially at right angles to the adjacent portions of the faces oftherespective small diameter curl portions, and the upper portions ofthesides of said body between and from closely adjacent to said shouldersbeing outwardly bent and said small diameter curl portions beingdownwardly and outwardly oil'set` to have their laterally outer facesdisposedsubstantially ush with the corre spondingy faces of the largediameter portions of said curl, in combination with a sliding coverarched both lengthwise and crosswise and formed of resilient material,side flanges integral with said cover and curved downwardly and inwardlyto snugly slidingly engage about and under `the respective outer facesoi.' said top edgecurl, and sharp abrupt cover stop shouldersrespectively extending inwardly and upwardly from the lower portions ofthe respective flanges and so located lengthwise thereof as to bedisposed between the v body stop shoulders on the respective sides ofsaid body and to be respectively presented in opposition to therespective cooperating body stop shoulders when said cover is applied tosaid body, said cover by its arched `formation and springy resilientnature pressing with its margin i against the top of said edge curl andpulling the lower portions of said flanges against the opposed faceportions of said edge curl. l i
